Device-to-Device (D2D) multicast underlaying a cellular infrastructure has recently investigated. In this paper, we propose a new interference management scheme for D2D multicast to increase the overall capacity and improve resource utilization. The proposed scheme includes two steps. First, in order to mitigate the interference from D2D multicast transmission to cellular networks (CNs), a dynamic...
In time-division duplex (TDD) system, precoding matrix for downlink transmission can be obtained from estimation of uplink pilots by using reciprocity. However, if the channel is time-varying, the channel difference would cause codeword mismatch between transmitter and receiver, which leads to performance degradation. In this paper, a codebook based precoding scheme is proposed for TDD systems to...
